RADIATOR.

Application fled Hay 1B, 1924. Serial No. 712,671.

This invention relates to radiators. The object of the invention is to provide a radiator comprising sections made of sheet metal, preferably sheet copper, `which. will 6 be economically efficient in operation, simple in construction, relatively inexpensive, suiliciently strong to withstand stresses due either to pressure or suction within the same and which will be very light as com ared with cast metal radiators, correspon ingly reducin shipping costs.

To e ect these objects, a radiator embodying my invention and improvementscomprises the various features and details of construction hereinafter described and claimed.

In the accompan ing drawin in which my invention is ful y illustrate Figure l is a side view of a radiator section embodying my invention and improvements.

Figure 2 is a or bottom.

Fi ure 3 is an enlarged sectional view on the line 3--3 of Fig. l, illustrating the arrangement of said sections in a radiator unit, one thereof being shown complete and the others only in part.

Figure 4 is a view of a radiator unit comprising a plurality of radiator sections, showing said sections as they would appear from the right/'side of Fig. 1, together with the connecting means therefor; and

Figure 5 is a fragmentary view of a radiator comprising a plurality of connected radiator units similar to that shown in'Fig. 4, particularly designed and adapted for heating by forced circulation.

Describing the invention with particular reference to the drawings, A designates a radiator section embodying my invention and improvements as a whole, said radiator sections consisting of plates 1, 1', having flat mar inal portions 2 extending entirely around t e same and which are respectively provided within the flat marginal portions 2 with corrugations 3, 3 which extend at an angle relative to each other, being preferably inclined at similar opposite angles relative 50 to a horizontal line when said Section is in plan view thereof, either top upright position. Said corrugations may conveniently be formed by stamping, the corrugations in both plates being stamped outwardly with reference to the contemplated plane of contact of the flat marginal edges of said plates, when connected to form the finished section, the relation being such that one set of corrugations will be tangent to the plane of contact of the marginal edges of said plates and the other corrugations will be tangent to the planes of the sldes of the finished radiator sections.

The plates 3, 3 are adapted to be igidly connected to form the radiator section A by soldering, welding or otherwise rigidly con- G5 necting the flat marginal flanges 2 of said plates together so as to form a tight joint.

lVith the construction described, it is obvious that when said plates 3, 3 are connected as described, the corrugations of the 7g plates 3, 3 of the radiator section, which are relatively convex, will rest in contact with each other at their crossing points, thus effectually preventing collapse of the sides of said radiator under suction.

The plates 3, 3', are provided with supply and return openings designated, respectively, 4, 4', preferably formed adjacent to opposite ends of the radiator section, each o said plates com rising an area 5 adjacent to the supply an return openings thereof which is flat and uncorrugated and the outer sides of which are in the planes of the outer sides of said radiator section.

Secured between the flat areas 5 of the S5 plates 3, 3 of the radiator sections A are hollow spacing members 6 which will prevent collapse of the sides of the radiator when subjected to tension applied thereto to draw two or more of said radiator sections into close contact with each other to form a radiator unit having a pluralit of sections, as will presently be describe Said spacing members 6 are preferably circular in shape and are secured in position by Hanging the edges of the supply and return openings 4, 4 in the sides of the radiator section, inwardly over the edges of the holes or openings in said spacing members, as shown at 7.

j provide a desired area of radiating surface.

For reasons` presently described, said spacing members or rin 6 are made in the form of spiders, comprising central hubs 8 connected to the ring portions thereof by arms 9, the hubs 8 being provided with holes 10 which are preferably concentric with the supply and return openings 4, 4.

To permit the heating medium-steam or hot water-which enters the supply openings 4 to pass from the hollow interiors of the spacing members or rings 6 into the interiors of the radiator sections A, and from said radiator sections into the spacin members 6 securedin the return openings 4 said spacing members are provided with ports 11 which open through their perimeters, thus connecting the openings within said spacing members with the interiors of said radiator sections.

A finished radiator will preferably comprise a plurality of sections A sullicient to In the preferable construction shown, any desired number of radiator sections A are adapted to be connected to form a heating unit of desired size by means of end plates 12, 12', applied to opposite ends thereof and which are rigidly connected by tension members 13 which provide means by which the f radiator sections may be drawn into close contact with each other, said tension members preferably comprising tension members applied at the supply and return openings 4, 4', thus insuring the formation of tight joints between the flat, uncorru ated areas 5 surrounding the supply an return openings of adjacent radiator sections. If found necessary, packing gaskets may be inserted between the surfaces 5 of adjacent radiator sections, but when said sections are made of soft ductile metal, as copper, no gaskets other than the flat contactlng surfaces 5 will be necessary.

In the preferable construction shown, the tension member 13 which extends through the return openings 4 of the radiator sections is tubular and is provided with holes 14, Fi 3, which communicate with different ra iator sections, forming vent openings therefor'. i

The lower ends of the end plates 12, 12 are preferably finished to form a supporting base for the radiator or, where the radiator is designed for use for heating by forced circulation, both the upper and lower ends of said end plates will be finished so that plates 15 may be secured thereto, Fig. 5,

. which, with the end plates will rovide a casingfor the top, bottom and en s 'of`said radiator, to the open sides of which pipe connections may be made, comprising a blower connection to one side thereof.

Preferably, also, the lateral marginal edges of the end plates 12, 12 are constructed and arranged so that any desired ,manifolds 18, 18 are adapte Vis not enclosed, the finished botto-rn flanges of said end plates will provide a supporting base for the radiators.

The end plates 12, 12', are provided with flanged supply and return connections, 17, 17 to which, respectively, suppl and return to be connected by means of corresponding flanged connections 19, 19.

To provide for venting the sections of different radiator units, when the system is not equipped with a vacuum exhaust, each unit is preferably provided with automatic, thermostatic vent valves. Convenient points of application of said 'vent valves are the supply and return connections 18, 18', both of which are provided with tapped holes, as shown at 20, to receive the threaded end of a vent valve. If vent valves are not used, the openings 20 may be closed by usual screw plugs21. y

While I have herein shown and described as havlng separate supply and return coniconections which communicate therewith at opposite ends of said sections, I do not desire to limit myself to the arrangement shown or to any particular arrangement that shown merely exemplifying any desire or approved arrangement of supply and return, which will vary with different heating media-as steam o1'- hot water-and differ ent return systems-as gravity or vacuum return. f

I claim:

1. A radiatorl section consisting of corrugated sheet metal lates connected at their edges to form a tig t joint, the corrugations of different plates crossin each other and comprising corrugations w ich restl in contact with each other at crossing points, said section being provided with an opening adapted for making a supply connection thereto, and the relation being such that the heating medium will traverse said sections crosswise of the corrugations in its side walls.

2. A radiator lsection as specifiedI in claim 1, which isv provided with openings in its side walls adjacent to opposite ends thereof, adapted, respectively, for making .supply and yreturn connections thereto.

sections substantially as specified in claim 1, and means for rigidly securing said sections together to form a radiator unit with corrugations of adjacent sections of the radiator in contact and the supply openings of different sections in communication with one another, said connecting means being constructed and arranged to exert pressure on corrugations of the outer sides of the extreme sections of the radiator, thereby prel0 venting the sides of the sections of the radiator from bulging when subjected to internal pressure.

In witness that I claim the foregoing as y my invention, I aiiix my signature this 6th 16 day of May, A. D. 1924.
